ast-types visit changes ast tree

I'm trying to use `ast-types` to do ast tree parsing in `eslint` rules. But it changes some ast tree nodes, thus not compatible with `eslint` rules

The code is
```javascript
var a = Array.from([1, 2, 3, -1, -2], function(x) { return x * x; });
a.uniq();
```

Errors are:

```javascript
AssertionError [ERR_ASSERTION]: Rule should not modify AST.

Start by reproducing the reported AST comparison with the provided JavaScript snippet, using ast-types in an ESLint rule, and inspect where traversal or parsing changes nodes. No files or tests are named; done means the resulting AST remains compatible with ESLint's rule validation without the added fields or other reported changes.
